This scenario for CIV5 without any mods and DLCs. This is huge map of North Atlantic with limited resources so to prevent AI from massive build up ( and huge lag ). This is fast turning and good balanced map for pleasant play even on slow computers.

Playable countries:
Russia
UK
Germany
France
Ottmans
Italy
Iroquois

and USA! Yes, I know that USA didn't exist in 1000AD but ... I made it for fan. And by the way, USA starts NOT ON THE LAND ;)
